In 2017 built a W7 UEFI, NVMe, USB3 installer (DISM video, USB3 driver integration and NVMe patch, W10 Boot files) that I then used to install W7 on a Lenovo Ideapad Y700 which is Class 3 UEFI. Been working fine since. Using Acronis, Macrium, or CloneZilla to do a full image restore/clone (to another NVMe stick - thank god) the resulting image won't boot. The symptom appears the same as GOP VGA.sys trying to write during "Windows Starting" screen just when the four color balls are about half way through their flight - top of screen video corruption (looks like a message trying to be written) and then system crashes. I have compared my working W7 on the Y700 to that of the cloned: BCD - bcdedit looks right Files in cloned EFI system partition - n:\efi\microsoft\boot appear correct Files in cloned \windows\boot\efi look right Tried regedit of services Vga and VgaSave to Start=4 still crashed. Tried setting BCD bootlog yes but no ntbtlog.txt. Any ideas? Please..
